Methods:
login
Starts the login process. It has one optional parameter, which should be an object with two properties:
logincaptcha, logintoken.
The logincaptcha is the user's answer to the captcha question
You will receive the logintoken if the login failed and the CaptchaRequired error code arrived
You must pass both the logincaptcha and logintoken if you must pass a captcha challange
getAuthId
Returns the value of the authId key from the response. If the login was success you will need to use this value to perform additional requests. You must put it into a the Authorization header like this:
'Authorization': 'GoogleLogin auth=' + googleAuth.getAuthId(),
getSID
Returns the value of SID key from the response.
getLSID
Returns the value of LSID key from the response.
isCaptchaRequired
If the login was not success and the user need to pass a captcha challenge this method will return true
getCaptchaUrl
Url of the captcha image
getCaptchaToken
You will need to pass it back to the google with the user's answer to the captcha if the login failed and captcha authentication required.
